Leg strength is considered an essential prerequisite in sprint running. The purpose of our study was to determine the relationship between peak isokinetic hip flexion and extension torques and 100-meter sprint time. Isokinetic torque was measured for the right hip muscles of 10 college males at angular speeds of 60 and 240˚/s. Three maximal effort 100-meter sprints with three minutes recovery between repetitions were performed on a separate day. Average sprint time was significantly related to hip extension measured at 60˚/s (r = -0.735, p<0.05) but not at 240˚/s (r = -0.501, p>0.05). Neither hip flexion at 60 nor 240˚/s (r = -0.546 and r = -0.405, respectively) were significantly correlated with 100-meter sprint time. Greater hip extension strength appears to be related to faster 100-meter sprint times. Increased hip extension strength should correspond with improved performance in 100-meter sprints.
